Answer:
2400 N (Newtons)
Explanation:
The weight of an object can be calculated using the equation:
Weight = mass * gravitational acceleration
Given:
Mass of the bed (m) = 120 kg
Gravitational acceleration (g) = 20 m/s²
Using the weight equation:
Weight = mass * gravitational acceleration
Weight = 120 kg * 20 m/s²
Weight = 2400 kg·m/s²
The unit of the weight is kilogram-meter per second squared (kg·m/s²), which is equivalent to the unit of force called Newton (N).
Therefore, the weight of the bed is 2400 Newtons (N).
